Dear Prof.Daniele

I would like to ask,
1. based on what we can conclude that SAR has good results and can use the APS options ( IP , IR , Tri.IR ) in the area of ​​the case study ? Can you attach some paper / reference, in order to we can understand more each parameter. It is not enough to judge like your say that “the APS looks ok and the tes…[Read more]

What do you mean that this is wrong? How can you say it’s wrong?
Don’t be afraid that a temporal noise in this case is not corresponding to a spatial noise.
In space you are applying several smoothing operations (interferogram filtering, unwrapping, APS estimation)
so, it is reasonable to expect a spatial correlation in the results
the problem is…[Read more]

Hi Yuxiao,

black borders has gone, thank you, however, footprints are now slightly different and they are not covering whole AOI. I’ll try to search for adjacent track based on Daniele’s suggestion from other forum thread and I’ll continue on testing.

Cheers

There are no better or worse things. They are simply different and they apply to different analysis/objectives.
Using the Amplitude (Models!) is useful e.g. in the case of temporary targets. You don’t use it in multi-master approaches.

The MST is by definition connected. However, even if theoretically interesting, the MST is practically not very…[Read more]

Thank you very much.
when I processing a multi-master images graph ，what is the different about using coher or Amps as a weight? which is better?
Should the MST graph all connected? And how many connections better?

I looks like the following:
– you are processing a multi-master images graph (it would be nice to see it)
– you are using the coherence as a weight in the inversion (is this the right choice? you need to look carefully at all your interferograms)
That message says that there are points for which some low spatial coherence values break the images…[Read more]

Hi Ana,
data are ok and everything works.
Did you try to save the geocoding window?
In such case, I believe you have overwritten and messed up the pcodes.
You can download the last pcodes version and it should clean up the installation.
Otherwise delete all files (but keep the license!!) and re-install the pcodes from the original tar file.

Dear Prof.Daniele

I have sent in your email perissin@purdue.edu,
Please check it

Best Regards,

ana

do the following things:
a. save the small area (“save” button in “small area processing” window). give it a name you like.
b. go to “dataset selection” and click on “export site param”
c. send me by email or wetransfer or whatever you want the .mat file of the small area and the ExportPar.tgz file

Dear Prof.Daniele

I have selected point first, after I select it and using Data Series, any tranding image will be appeared.
But, the fact, If I select point, the left-below box show me “Error in data selection”.
The image example from Def.Trend I have included before.

Best Regards,

Ana

select a PS point first

Dear Prof.Daniele

I have included error file below,
Matlab R2013a was installed

Best Regards

Ana

Send the errors please.
By the way, are you using the pcodes version? What’s your Matlab version?

Dear Prof.Daniele

I have tried another parameter likes Deformation Tranding (Def.Trend) and Cumulative Displacement (Cum.Disp) to get time series deformation graph data. But always any error If I check “Data Series” tools, in other word is nothing image ploting to be resulted.

Best Regards,

Ana

Hi Ana,
we are going to add a check in the code. Anyway, please notice that you are trying to display the quantity “PS Type”, which for sure you did not calculate in your analysis. So, for the moment, simply choose an other quantity to display…
